The SUNY system is “actively considering” mandating that all of its 64 campuses adopt emergency text-messaging programs that could instantly warn students via their cellphones in the event of a massacre like the one at Virginia Tech, officials said.

SUNY – which has more than 417,000 students – may also adopt a “reverse 911 system,” in which students and staff would be called en masse on their cellphones with “a specific” voice message about a threat or emergency, said SUNY spokesman David Henahan yesterday,

Two SUNY schools – the Buffalo and Cobleskill – already had mass text-messaging alert systems in place before SUNY New Paltz launched its own last Friday. As of yesterday, more than 500 of New Paltz’s 8,000 students had signed up for the system. Spokesmen at several New York City-area private universities told The Post yesterday that they, too, are seriously eyeing adding text-messaging options to their emergency plans because of the Virginia Tech killing spree.

Administrators at Dowling College in Suffolk County plan to discuss a text-messaging system at a security meeting. The college’s vice president of student services, David Ring, said that the benefits are obvious.

“Virtually every student now has a cellphone, and they text as much as they talk.” Additional reporting by Frederic U. Dicker
